AUTOMATIC FIRE EXTINGUISHER.

Refiling of application Serial No. 756,657, filed March 25, 1913. This application filed July 28, 1919. Serial No. 313,926.

1 0 all whom it may concern Be it known that I, Cniinnlvon lune-Davis, a citizen or the United States, residing at the borough of Brooklyn, in the county of Kings, city and litateoi New York, have invented certain new and useful Improve ments in Automatic Fire l lxtinguishcrs, of which the following a specification.

The main object oi my invention, in its broad scope, is to provide an. automatic lireextinguishing apparatus, by the use of which any suitable fire extinguishing material oi any fluent fluidal form and cor quently capable of liowage, such as line granular powder, water, chemical solutions, or gas, or a combination of any two or more thereof, upon the surrounding temperature reaching an abnormally high point, will be automatically-projected from the rc pta le oi the apparatus in practically all s, rounding dimensions of space; ach of which devices will be individually complete within its-1 and not dependent upon any exterior mechanism. for actuation, wiich ma; be shifted into a new position by any ordinary me chanic; which may be easily refilled and replaced after actuation many times; and which will not deteriorate thru age, etc.

The particular form of en'ri'iodiment of my inventionset forth herein, is one form thereof more particularly designed and adapted for use in distributing lire extinguishing material of the dry powder form; but, with little it' any modification ot the construction shown, and without departing;

from the scope of my invention, the some may be made capable of use with any other form of flue t liuidul lire cratin ilishing ma terial.

in the preferred form in which l have :lound my broad invention to be best applicable to bring about the most perfect distribution oi the tire extinguishing;- fluent tluidal material thruout the adjacent fire zone, the receptable revoluhly mounted in a gyroscopic frame, which pendulously supported by a chain or other flexible support to a ceiling ring or hook, in suci manner that such support will be t 'sioually twisted upon rotation of such frame, and will be again imtwisted by the action of gravity when the torsion has reached its limit, For this purpose have found a double (hain (as shown i in the drawings) particularly applicable and desirable. In this form of the device the rotation is given to the receptacle by a motor-spring contained or carried by the receptacle, and norcally locked by a suitable thermo-trip; and the action of this spring when released, rotates the receptacle within the gyrosropic trams, and also vibrates such frame so as to twist the double or unswiveled chain or flexible support, and this combination of forces, coupled with the vibration of the tran'ie gives a gyratory, pendulous and rising and falling motion to the entire device which it impossible to describe'in special terms, but which results in distributing the fluid in the receptacle equably thruout practically all dimensions: of space, both above and" below, and in the immediate vicinity of the po nt of suspension.

' lily said invention is fully shown and described in the-following specification, of

which the accompanying drawings form a part, wherein similar lettersor numerals oi re'lierence gnate lik or equivalent parts wherever found thruout the several views, and in which Figure 1 is a side View partially in central. longitudinal section, of the main portion oi one form of my improved automatic fire extinguisher, designed for distributing a lire extinguishing powder upon the adjacent fire zone.

Figures 6 and 7 are views in detail, b t on slightly different scales, each partially in section, of my improved fusible-solder thermo-trip, which I prefer to use as the automatic thermo-release in my said improved automatic lire-extinguisher.

Figure 8 is a side view of a. portion of the lift-ratchet and its actuating lever, the movement of which lifts the spider so as to uncover the outlet orifices ot' the receptacle; and Figure 9 is a view of the entire device as it appears when in position and ready to be automatically set into operation when the temperature reaches the predetermined abnormally high point.

lleterriug to the drawings The reference letter A designates a frame, ol any suitable shape or contour, usually of the rectangular form shown, made of" any Sllllfll')l6 material, but usually of cast metal, iron. steel, bronze, etc, and for convenience oi description such frame will be here-inafter referred to herein as the gyroscopicframe? lVithin such frame is revolubly supported the receptacle B, usually formed of any suitable sheet metal, and usually but not necessarily of the cylindrical form shown, the bottom plate 1 thereof being centrally swaged upward and inward at the center as shown at 2, to form the motor-spring cavity 3, and also provided at the periphery with the annular groove l, into which fits the lower edge of the annular closure-ring 5; the joint at such groove, and also that betweenthe top of such ring and the peripheral wall 7 of the receptable being usually made air tight by seals 6 and S, 0-1? any suitable easily frangible material.

The annular wall 7 of the receptacle is usually of: any suitable sheet metal, and within the same and formed of similar material is usually and preferably located a deflecting annular wall 9 of the truncated cone form shown, with the base adjacent to the bottom plate 1, which wall is swaged outward and then inward at a plurality of points so as to form securing brackets in, i

by which such deflecting wall is secured to the outer wall 7 and bottom-plate 1, usual- 1y by suitable rivets. as clearly shown in In any event, and especially in the devices used for the distribution of a fire ertinguishing fluidal material in the form of a dry powder, an outlet orifice 11. usually in the form of an annular slit broken only by the brackets 10, is left between the lower edge of the annular receptacle wall 7, and the bottom-plate- 1, of sufficient width to permit of such material being thrown violently outward freely there-thru by centrifugal force when the receptacle is rapidly rotated, which slit is usually of about one-half (9;) an inch in width, but where liquids are to be used, one or more circular orifices. or any shaped orifice more suitable for delivering liquids of watery aqueone like character, are used .inpreterence to orifices oi the slit form shown; and I do not intend to limit myself to any particular form of such peripherally located centrifugal outlet delivery orifice or to any par-- ticular number thereof.

In the dry powder form of device shown herein, the top-plate 12 of the receptacle is usually secured to the annular peripheral wall '7, by al'olded lock-joint 13, which is also usually and preferably made air tight by soldering. Such top plate is provided. as shown in Figs. 1. and 3, with aplurality of openings li, (shown in dotted lines in Fig; 3) usually four in number, each of which is provided with a cover-plate 15, hinged to the top-plate 12, byhinges 16; and such cover-plates are provided with downwardly depending side portions 17, so that when such cover-plates are raised at the forward unhinged ends so as to be pivotally thrown upward upon their rear hinges 16, such cover-plates taken all to gether will form a four-winged or bladed force-fan, the wings or blades of which are each provided at the outer end with depending flanges or end portions projecting in the direction of the draft; which fan so formed upon the rotation of the receptacle will cause a blast of air to be directed down into the receptacle; and until the level of the fluent material, at least atthe peripheral edge of the same is below the upper edge of the outlet delivery orifice or slit at the bottom or" the inner wall 9, this blast will be wholly forced down thru the annular space between the outer wall 7, of: the receptacle, and the inner deflecting wall 9, and out thru the delivery slit: 11; after which a portion will pass down within the wall 9, and both streams be directed out, thru slit 11; such blast thus greatly assisting in the far and free distrilnition ot the fire-extinguishing material whether of powder, or any other suitable fluent 'l'luidal form. And such combined fanblades and coverplates 15, are each provided with the liftclips 18, formed integral therewith or secured thereto extending over the radial arms 19, of the lift-spider C, the lift-arms 20, of which are secured at the lower end to the closure-ring 5, usually by being screwed or riveted to brackets 21, formed integral with or secured to such ring.

The top-plate 12 is usually spun or struck up from thin sheet metal and is provided at the center with the cylindrical annular liit-v ratchet cavity 22, upon the inner annular wall 23 of which reciprocates easily up and down the central ratchet portion 24 of the lift-spider C, raised by the lift'ratchet 25, upon the movement of the lift or trip-lever 26, (Figs. 1, 3 and 8) upon the rotation of the receptacle as hereinafter described. The

joint between this wall 23 and the central pivot-standard is usually made air tight by soldering, or in any other suitable man ner. j

7 As shown in Figs. 1 and 2, the receptacle B is secured to the bottom Supporting spider- D in any desired manner, usually by rivets 27 passing thru the bottom-plate 1 of the re ceptacle as shown. Such spider D is usually termed 111 one piece of cast or drop forged metal, iron, steel, brass, etc, having the een-,

tral cone-shaped portion 29, from the center of which xtends upward the central shaft 30, formed integral with such portion 29, in

' secured to or formed integral with one of the standards of 29; and the inner and central end of such motor-spring is provided with a like securing perforation by which the same may be secured to the motor-spring shaft F, by being slipped over the headed securing screw 36, firmly screwed into such shai't. Such motorspring shaft F is provided at the top or inner end with the pointed pivot pin 37, fitting into the bottom journal (bearing cavity 34, of the spider standard 30, and at the bottom with a journal cavity 38, similar to 3-1, and hushed in the same manner, adapted to receive the bot tom pivot-pin 52 secured in the frame A by a drive-pin or screw 53, and formed integral with the secondary-cable support ring 71. Such motor spring shaft F is also provided at the outer and lower end with a suitable square or nut portion (Figs. 1 and 4), upon which is tightly sweated the ratchetplate so, (shown in detail in Fig. 1), so that the two will simultaneously rotate, which plate i0 is provided with the ratchet lockslots 11, the safety securing bolt slot 4C3, and at the outer end oi? the side extension .12 thereof, with the side trip-lever securing slot 4:4:-

In assembling, the inner end of the motorspring E is slipped over the screw 36 on the motor-spring shaft F, and suchs iriug and shaft slipped up into the motor-spring cavity into the position shown in Fig. 1, the ratchet-plate 40. having been 01" course sweated on to the motor-shaft, and the antifriction sleeve placed in position in the cavity 38, and the outer end of the motorspring is then slipped over the securing stud 36, and the ratchet-plate secured against rotation by the insertion into position at the securingsatety thumb-screw 1:5,havinc? the thumb-piece 46, into spider D, after which the binding Wires or clamps holding the spring under tension are removed, and the combined spring securing and dust-plate 28, which is usually in two parts, the split thereof not being shown, is secured in place so as to form a dust-proof bottom for the motor-spring cavity, usually by means of screws 28, as shown in Fig. 1. Usually an anti-friction washer ofsoft material impregnated with plumbago, etc., shown at 1 7, is interposed between the dust-plate 28 and the ratchet-plate to, to minimize the friction, and at the same time close the central orifice thru which the shaft F passes against the entrance oi? dust.

After the motor-spring in position, the annular closure-ring 5, is next slipped down into position so as to close the outlet orifice or slit 1].. of the receptacle B, and such receptacle filled with the required fire-ertinguishing fluent fluidal material thru one or more of the air inlet orifices 14. The combined cover and fanplates 15 are then forced down into the closing position shown in Fig. 1, and the joints thereof with the top plate, as well as the joints of the closure-ring 5, with the bottom plate 1, and receptaclewall 7, for the purpose of preventing deterioration of the :tluidal fire-extinguishing material t'hru admission of air, vapors or gases to the interior 'thru such joint, are all sealed air-tight with a material which will quickly give way so as to allow the joint to easily open when required, such as sealing-wax, paraffin, etc, or even by the same. fusible solder used in the thermo-trip, which melts at F. j l

The lift-ratchet is then slipped into position in the ratchet-cavity and the lift spider ratchet 2+2, 1 and 8), slipped down over the same, and by a slight turnii'ig iox'ement of both lift-ratchet 25, and littspider C contra clockwise toward the leftin Fig. 3, on the receptacle B, the top radial arms 19 oi such spider are swung under the lift-fingers or lugs 18, of the cover fanplates 15, formed integral with or secured to such plates, in such manner that the lifting up of the lift-spider (l by the action of the radial arms on such lingers or lugs will force such cover tan-plates into the raised and open position, so as to uncover the airinlet orifices 14; and after the spider C is thus placed in position the same is secured firmly to the closure-ring 5, by suitable screws 21, passing thru brackets formed integral with and extending upward from closure-ring 5, and screwing into the lift-bars 520, which are but downwardly depending integral extensions of the radial. arms 19. 01" the liit-spider U. i

The throw or triplever 26 of the liftratchet L25, o'l spring-steel, and extends from the litnratchet, (to which it is firmly iii secured, usually by a screw or screws as shown in Fig. 8), out from under the central boss portion of the lift-spider C, which forms a cover-plate for the annular liftratchet cavity 22, thru a throw orifice or slot a9, (Fig. 1,) of about the length of one fourth of the periphery of such cavity and boss; and such spring throw or trip-lever 26,

trip-rail upon the initial rotation of the receptacle, the same will by its own resiliency be forced down into the position shown in dottedlines in Fig. i, so as to thereafter permit free rotation of the receptacle for the reason that in such depressed po; tion the outer end 90 thereof will no longer contact with the trip-lug 91, of the gyroscopicframe A. The position of all the parts as shown in full lines in Fig. 3, are those such parts are in, when the device is suspended ready for operation, as shown in Fig. 9.

The receptacle B having been filled and sealed as hereinbefore described, the same is slipped into the gy roscopic-frame A, and the pivot-pins i and placed in position in the central bosses of the frame and secured therein by drive pins 53, so as to pivotally and revolubly mount the receptacle within the frame (anti-friction washers of plumbago composition, etc., 55, being usually placed in the positions shown in Fig. 1, be-

- 'een the frame and receptacle to lessen the friction) and the thermo-trip G is then socured to the frame A, by means of the screws 57, passing thru the frame A and screwing into the mainplate 60, of such thermo-t-rip, as shown in Figs. 6 and 7, and the safety cotter-pin 58, passed thru suitable registering holes in the top end portion (Figs. 1, 6 and '2') of the tripdever of such thermo-trip, (fl, and thru the downwardly depending lin 66 of the supporting spider D, so as to prevent release and rotation of the receptacle during transportation of the device.

As shown in position in Figs. 1 and 9, and in detail in Figs. 6 and 7, the thermo-trip G, in the form of my invention which I prefer to use, comprises a brass securing or mainplate 60, (adapted to be firmly but removably secured to the gyroscopic-frame A, by suitable screws 57) which is provided with the rock-lug 61, having the knife-edge 62, againstwhich normally rests and on which when actuated rocks the thermo-trip releaselever *3, (located in a slotopen' to what is the left of Fig. l as hereinafter described) which is secured to the main-plate 60 by a film 64, of easily fusible solder, usually of the well known composition used in autoinatic lire extinguishingdevices which fuses at approximately 155 F. Such thermo-trip may be of any suitable desired form, but that shown I have found efficient for the purposes desired; and in tl e lrawings Fig. i shows the trip in position on the gyroscopicframe; a port-ion of which frame, as well as part of the trip-mechanism are broken away in order to more perfectly show the construction. Figs. 6 and '7 are views partially in section respectively vertical and horizontal looking from the left and from the top of Fig. 1, save only that in Fig. 7, I have not deemed it necessary to show the trip-able attached thereto, for the reason that l have shown such trip-cable attached in one manner in Fig. l, and in a slightly modified form of attachment in Fig. 6, and have also shown therein the rock-lug 61, at the end of which is integrally formed the lug (58, be tween which and the main-plate ('50 is left a slot to receive the shank of the ti.-i 3lever ('33.

To the lower end of the thermo-trip re lease lever 66, nly secured (Figs. l, (3 and 9), usually by soldering the same there to as indicat l at 69 the end of the sec ondary supporting trip-cable 70, which preferably formed into a loop 70 adjacent thereto, and has the bight of such loop secured either to the lower end of the trip-lever 6-3, by low-fusible thermo-release solder, indicated at 65 of Fig. 1 or to the mainplate 60, in the modified form of construction shown in Fig. 6; and from the solderloop connection so made the trip-cable passes thru the sup porting-ring 71, to the secondary hanger-ring or support 3, (Fig. 9) supporting the extinguisher by the contact of the weight secured to the end of tripcable 70, with the outer right hand face of the hangei ring 73; whereby upon the thermal release. of the trip-lever 6S, and the pendulous vibration by gravity of the cxtin guisher (zr' shown in dotted lines) such triplever 63, passing freelythru the ring -Tl, such trip-lever and the supporting trip-cable 70. will be drawn l'iaclc by the gravity of the weight 85, thru the hanger-ring 73, until the stop 86, rigidly secured to such cable, Will leave the cable '70, carrying the trip-lever G3, at one end, and the weight 85, at the other, suspended by the center by the ring 73, full y out of interfering contact with the device during its operative movements, all as clearly shown in dotted lines in said l ig. '9.

The receptacle, thermo-trip, etc, having all been placed in position in the gyroscopicframe A, as hereinbefore described, the curved r ar end portion or supporting lug H, of the ratchet-plateloch-bar 75, (Figs. -l-

llU

iii

and 5), is passed thru the perforation T6,in the gyroscopic-frame A, and on and over the end of the spring 77, (Figs. 1 and 4) secured by a screw 79 to a lug T8 forn'ied integral with or secured to the frame A; and such spring 77. normally tends to force such lock-bar 75, down into the position shown in dotted lines in Fig, 5, so as not to interfere with the free rotation in the frame A of the receptacle B, and the like rotation of the ratchet-{date 420. Such lock-bar is then lifted up into the position shown in in full lines in Fig. 5, and the end piece or extension 42 of the ratchet-plate -10, swung against the tension of the spring E anl then dropped back into the slot of such lockbar 75. In order to permit of free movement in both directions relative to the lockbar 75, of this end piece or extension 42 of the ratchet-plate 40, the same is preferably slightly twisted so as to have normally the slanting position shown in Fig. 5; and the lock-bar 75, is so loosely fitted by its supporting-lug 7 1-, in the perforation 76, in the gyroscopic-frame A, that the outer free end carrying the slot 80, will move freely in all directions, up, down, and. sideways. with a universal loose rocking motion at the joint formed by 74, and 76, so that it will commodatc itself to the outward movement from the slot 80, of the end-piece i2, of the ratchet-plate 40, upon the operation of the apparatus, as hereinafter more particularly described, in such manner as to release 42 from the slot 80, and permit such loclcbar 75, to drop down into the position shown in dotted lines in Fig. 5 where it will no longer prevent rotation of the ratchet-plate 40, in either direction.

The parts being in the position shown in Figs. 4- and the safety cotter-pin 81, (Figs. 1 and 4-) is passed thru the perforations formed to receive it in the lock-bar 75 and the downwardly extending end flange 82 at the end of the extension 49. of the ratchetplate &0; after which the safety thumbscrew 46 is usually removed, and the device, locked against accidental release by the safety cotter-pins 5S and 81. will be ready for shipment.

When in position ready for use, the device is supported from a point which when the same isin operation will be the top thereof. by any suitable means which will permit of gravitational pendulous movement of the gyroscopic-fiame; such supporting means being usually flexible and unswi'veled. and l have found in actual practice a double chain 84, passing thru the ring 51' of the top pivot pin 51, and secured to a ceiling ring or support 83, (Fig. 9). highly efficient for such purpose. For I have found by actual experiment, and operation that when released, by the consequent rotatire constant movement of the receptacle within the gyroscopic-frame, while at the same time such gyroscopic-franie is performing pendulous swinging moven'ients, the unswivelled double chain support H t. will be twisted upon itself first in one direction, and then in the other; and that the combination of all. the various motions ,of the whole and the sore a] differentially moving parts of the device, will be practically indescribable, in plain terms, by reason of their extreme swiftness. But I have found that the twisting and untwisting of the unswivelled chain, gives rise toa rising and falling of the gyroscopie-frame, and also to what may be best termed an exa gerated nutation, or nutative movement, 01" the gyroscopic-frame, and the receptacle retained and rotating in such frame; which will cause the axis of rotation of the receptacle to successively assume almost an infinite number of positions; which consequently causes the tluidal fire-extinguishing material, to be violently centrifugally discharged, in practically an infinite number of special planes, up, down, horizontally and diagonally to the horizontal and vertical; whereby such tire-extinguishing fluidal. material, if the room be a small one, say eight or ten feet square, will be thrownviolently against the ceiling, floor, and four walls, in an astonishingly equable and even distribution, thus being brought into contact with the adjacent fire-Zone, irrespective of its spacial dimensional location relative to the ceiling ring or support 83. Y

The device is also further supported in position to be gravitationally vibrated upon the main support when thermally released by the secondary supporting tripcable '70 secured at its lower end to the trip-lever (313, of. the thermo-trip G, which passes thence thru the lower or pivot-pin ring 71, (Figs. 1 and 9), to and thru a supporting ring or ceiling support 73, (Fig. 9), and is provided at the outer and free end with a weight 85, and has secured thereto between the ring 71, and support- 73, a stop disk 86, too large to pass thru the support 73, so as to holdthe cable suspended out of the way of the moving device, and in the position shown in dotted lines in Fig. 9, when thermally released.

After the device has been suspended from the telling supporting hooks or eyes 83 and '73. (Fig. 5)), in the manner deacribed.v the safety cotter-pins 58 and 81. are removed, and thereafter the device is ready for auto uiatic-thermal actuation upon the surrounding tcniperature reaching the proper high point at which the thermal solder joints 6 and 69' will fuse. V7 hen this temperatrn'e is reached, the smaller supporting fuse 69' (for the reason that it supports a large portion of the weight of the device) will part first, and the device falling by gravity the length of the bigl'it or loop mfit'i-iis will cause such a sudden strain. to be brought upon. the lower luj llU

end of the release-trip-lever 63 (the thermal solder joint 64 of which has also melted), as to rock the same upon the knife-edge 62, of the rock-lug 61, of the main-plate 60, of the thermo-trip G, and throw such trip-lever completely out of the slot of such main-plate, whereupon such'trip lever upon the continued downward swing of the device will be drawn out thru the ring 71, and into the position shown in dotted lines in Fig. 9, by the action of the weight 85 secured to the other end of the secondary supporting trip-cable 70. The instant the release trip-lever 63 re leases the stop-lug of the supporting bottom spider D, the force of the motor-spring E exerted upon such spider thru the securing lug 36, sets the receptacle into rotation upon the pivot-pins or pintles 37 and 51, within the gyroscopioframe A. The motor spring E is of such power that when the receptacle has all but completed one complete revolution, and the trip-end 90 of the triplever 26 of the lift-ratchet 25, comes in contact with the side of the downwardly and inwardly projecting trip-lug 91, (as shown in Fig. 1, at upper right-hand corner, in full lines with contacting endof lever 26, in dotted-lines; and also shown in dotted lines at upper left-hand corner of Fig. 3) which trip-lug 91, is formed integral with the side or upright member of the gyroscopic frame A; and against the opposite side of which trip-lug, such trip-lever 26, was in close abutment (as shown at the left side of Fig.

" 3) up to the moment of the thermal release,

and the consequent rotation of the receptacle by the action of the motor-spring E.

And while such trip-lever 26 will thus be momentarily stopped against further rotation upon contacting with 91, the receptacle will continue to rotate. The stopping of the trip-lever 26 will also cause a slight relative stopping of the lift-spider C, whereby the closure-ring 5, will be given a slight rotative movement upon the receptacle sufficient to break the frangible seals at the top and bottom of the closure-ring 5. Such relative rotative movement is very short, say from 4 th to 31th of an inch at the utmost; and is limited by the stop-pin 92. rigidly secured at its lower end to the covering top-plate 12. of the receptacle B; which stop-pin is of such length as to be always located. in the stop-slot 93, formed in and thru the central hub portion of the lift-spider C, even when such lift-spider is in the fully raised and outlet opening position. Inasmuch as in the construction shown in the drawing the expulsive rotative movement of the receptacle B, within the gyroscopic frame A. is contra clockwise toward the left (indicated by the arrow 3 in Fig. 3) the seal-breaking relative rotative movement of the spider C per contra, is clock-wise toward the right, as indicated by the arrow 2. in such Fig. 3. Before the thermal release of the device, and when in the position shown in Figs. 3 and 9, the stoppin 92, is located at the extreme left-hand end of the slot 93, and when the relative rotative movement of the spider C, on the re ceptacle B, is brought about in the manner just described, the stop-pin 92, by its abutment against the righthand end of the stopslot 93, of the spider C, will instantly cause the spider to come to rest relative to the receptacle, by again taking up the rotative movement of the receptacle, while the triplever 26, still being in the raised position and stopped by the trip-lug 91, will still remain stationary, holding stationary with it the lift-ratchet 25, secured to its inner end;

And thereupon the continued rotative movement of the lift-spider C, with the receptacle, will cause the lift-ratchet 2 1, of the spider to ride up on the ratchet 25, which is rigidly secured to or formed integral with the lift-spider C, so as to lift such spider, and consequently the closure ring 5, so as to open and uncover the annular outlet orifice or slot 11; and as soon as the coacting flat surfaces of the teeth of the two ratchetwheels 24 and 25, indicated in Fig. 8, at 24 and 25, have slid upon each other so as to hold the lift-spider C in the raised position, the resilient spring trip-lever 26, will pass off from the segmental trip-rail 50, as shown in dotted lines in Fig. 3, and will be forced by its own resiliency down into the position shown in dotted lines in Fig. 1, so as to clear the stop-lug 91 formed integral with the gyroscopic-frame A, after which such triplever 26 will of course be free to rotate with the receptacle.

lVith a motor-spring of the ordinary coil clock-spring form shown, made of suitable spring steel, and of say about 18 feet in length, about one thirty-second of an inch in thickness, and about one and one quarter inches in width, wound into a close coil of about three and one-half inches in diameter, contained in a motor-spring cavity of about six or so inches in diameter, and with a receptacle weighing when filled from thirtyfive to forty pounds, I have found. that the spring at just the instant of the contacting of the lever 26 with the stop-lug 91, will have an inertial force of approximately somewhat over forty pounds; and that by the time such spring has'reached the limit of its unwinding, the receptacle will be rotating at a. high rate of speed, estimated by experts to be at between 800 and 1000 revolutions per minute, and such revolution will not cease for about eight or so minutes, altho the receptacle will have been fully emptied of its contents by the centrifugal force, in less than two minutes. This distribution of the fire-extinguishing fluent fluidal material is greatly assisted by the actioaof the deflecting vanes 95, and also by the blast of air driven down thru the annular space 96, between theouter wall 7, and the inner conical deflecting wall 9, of the receptacle, and out thru the annular out let orifice or slit 11, by the fan-like action of the cover fan-blades 15, which have been lifted into the open position so as to uncover the air-inlet orifices H, by the lifting action of the radial arms of the lift-spider C, exerted upon the lift-clips or lugs 18 of such cover-platesor fan-blades 15, as such spider C is forced upward by the action of the lift-ratchet 25, hereinbefore described.

When the motor-spring E has fully unwound, the continued rotation of the receptacle automatically withdraws the lug 36 therefrom, whereupon the outer inwardly curved end 98 of such motor-spring is by the natural resiliency thereof forced back toward the center and into the position shown in dotted lines in 2; and immediately upon such release some rotative motion being communicated to the motor-spring shaft F, by the minimizedslight friction exerted upon the pivot-pin 37 by the swiftly rotatinp; receptacle such motor-spring shaft will begin to rotate in the same direction as the receptacle upon the bottom pivot-pin 52, carrying with it the ratchet-plate et), the end-piece or extension 42 of which is immediately thrown out of the securing-slot in the end of the ratchet-plate lock-bar 75, and into the releasing position shown in dotted lines in Fig. 5; and the instant that such lock-bar 75 is thus released from contact with the extension of the ratchet-plate, the spring 77. will force such lock-bar down into the position shown in dotted lines in Fig. 5, so that such lock-bar will be wholly below the upper edge of the bottom-bar of the gyroscope frame A, so that. thereafter the ratchet-plate will be free to rotate in such frame without coming in contact with such lock-bar 75. l I p The receptacle having; been thus emptied, in order to render the same ready for use without return to the factory, the same is taken down from the support 83, and the screws 21 securing the lift-spider C to the closure-ring 5 removed, and the spider lifted off, and the ring 5 pushed down into the closing position shown in Fig.1,and hermetically sealed by soldering as hereinbefore described. 'lhereceptaele is then refilled by way of the orifices 14, and the liftspider replaced and secured to the closurering; 5 by the screws 21; the trip-lever 26 having first been of course swung back and over the segmental trip-rail 50, and into the position shown in full lines in. Fig. 3, and after the receptacle is filled the joints between the receptacle top-plate 12, and the cover fan-plates 15 are sealed as hereinbefore described. Such filling may of course best be done by first removing the receptacle from the gyroscopioframe, by the removal of the pivot-pins or pintles 51 and 52, but this is not essential; and when the receptacle is so removed, the dust-plate 28 is taken off, the outer end of the motor-spring E is slipped over the securing-lug 36, and the motorspring rewound by rotation of the ratchetplate 4.0 (usually by the use of a suitable spanner, not shown) after which such ratchet-plate is locked in position by the insertion of the safety thumb-screwbolt 15 thru the slot 13 of such ratchet-plate 10, and the screwing of the same into the spider D, as shown in Fig. 1.

When the receptacle is not removed from the gyroscopic-frame A for such filling and rewinding, the operation is slightly different, being as followsz-The dust-plate having been removed, the outer end of the spring E is secured to the lug 36, and the dust-plate having been replaced, and either the old thermo-trip resoldered, or a new one, secured in position, the safety cotter-pin 58 is then passed thru the trip-lever 68, and the fin 66 of the bottom-spider D, so as to lock the receptacle against rotation in the gyroscopic-frame.

The various parts having been thus assembled and in operative position, the removable pawl-plate 100, provided with the spring-pawl 161 which is adapted to coact with the pawl-slots er of theratchet-plate 10, to prevent retroactive rotation of such ratchet-plate by, the action of the motorspring Eywhile the same is beingwound up, is placed in position on the bottom-bar of the gyroscopic-frame A. and secured in place by a pin or screw 102. (Fig. 1).

The motonspring E, may then be wound up, either by pressure exerted upon the extension 412, or by the use of a suitable spanner (not shown) adaptedto fit into the pawlslots 41, of such ratchet-plate 40. The motorspring E having been fully wound up the of the ratchet-plate extension 42. isallowed to slip back into the securing-slot 80, of the. release lock-bar 75. and the safety cotterpin 81, and safety thumb-screw bolt 4:5, having been placed in position. the removable pawl-plate 101, (which is only in position on the frame A. during such rmrinding) is removed; and the device having been again suspended in position by the cables Stand 70, (Fig. 9) and the safety cotter-pins 58 and 81. having been removed. the device will he again ready for automatic action upon the surrounding temperature reaching the proper abnormally high point: all hereinbefore described.
